Thanks to the developers and quality engineers who worked hard to make this branch a rock solid release, and of course for everyone who tested the betas tirelessly: Your feedback was invaluable.

If coming from ZD 1.0 we highly recommend you read the version notes as 2.0 will install separately. Trust us though - from performance increases, an enhanced aggregated inbox, cross mailbox functions, tabbed composing, a right-hand third reading pane, calendar fish-eye view, to newly bundled Zimlets like the social tab - it's definitely worth upgrading.
